ABSTRACT:
An antenna with a dual end resonant slot array feed improves the bandwidth performance of a resonant slotted waveguide planar array antenna. The dual end resonant slot array feed includes a tee junction which may be either an E-plane or H-plane, two waveguide sections, and two E-plane waveguide bends. The two waveguide sections are formed by a septum mounted in a slotted waveguide for separating the input tee junction from the slots of the slotted waveguide. The ends of the septum coacting with the ends of the waveguide to form the E-plane waveguide bends. Thus, resonant feeding of the series-slot waveguides is achieved by the opposing traveling waves thereby eliminating the need to use resonant short circuits, cavities, or folded short circuits. Further direct coupling to the series slots directly adjacent to the E- or H-plane feed point is avoided by introducing the septum between the feed point and the row of slots.
